The story line was really beautifully plotted. You never feel bored at any point of time. They havent dragged it too long either. The leads have done a perfect job for their role. Overall its a 10/10 for kang bok soo and son soo jung. Teacher park also played an impressive role. Given the chemistry and romance bw the leads, its amazing although cringe. But you would wish for a boyfriend like Kang Bok Soo after watching this??. If you want to binge watch something, you can go with this. And you wont regret !!
